Find an equation of a line that has a slope 7 and passes through the point 3,11

Answers

You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.

Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.

11 = 7*3 + b

Notice the only variable left is b, so you’ll find b this way.

11 = 21 + b and then subtract 21 from both sides:

11 - 21 = b

-10 = b

Plug that back into the equation and you have y = 7x -10

The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?

Answers

9514 1404 393

Answer:

  1125

Step-by-step explanation:

The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.

  $5.60n = $6300

  n = 6300/5.6 = 1125

The company should sell 1125 units per month to break even.

He Owes –$18

He gets +$30 for cleaning the house.

He'll simply have 30–18 = $12 after paying the debt he owes his Mom.

Answer:

$12

Step-by-step explanation:

If Ryan owes his mom 18 dollers, that means he has to pay his mom 18 dollers and then gets 30 dollers in return.

so the expression is -18+30 which is 12 dollers. So Ryan will have 12 dollers extra after paying is mom.

A long distance runner does a first lap around a track in exactly 50 seconds. As she tires each subsequent lap takes 20% longer than the previous one. How long does she take to run 3 laps?

Answers

9514 1404 393

Answer:

  182 seconds, or 3 minutes 2 seconds

Step-by-step explanation:

The second lap takes ...

  (50 s)(1 +20%) = (50 s)(1.2) = 60 s

The third lap takes ...

  (60 s)(1.2) = 72 s

The three laps take 50 +60 +72 = 182 seconds, or 3 minutes 2 seconds.

the scale from a map to actual distance is 2.5 cm to 620 miles the distance on the map between Chicago and Boston is about 3.5 cm what is the distance between Chicago and Boston​

Answers

Answer:

868 miles

Step-by-step explanation:

cm to miles ? are you sure you got the problem description right ? because cm are part of the metric system (mm, cm, meters, kilometers), while miles are part of American/ UK systems. and they don't deal with cm.

but ok, so, we will not deal with conversion rates, we will just apply the scale factors.

2.5 cm <-> 620 miles

3.5 cm <-> ? miles

that is determined by the factor to go from 2.5 to 3.5 cm. the same factor then had to be applied to the miles.

2.5 × f = 3.5

f = 3.5 / 2.5 = 7/2 / 5/2 = 7/2 × 2/5 = 7×2 / 2×5 = 7/5

=>

620 × 7/5 = 868 miles

Explanation needed it the answer

Answers

Answer:

8 units

by step explanation:

Since AB and DC are parallel to each other;

Then x + 2x = 180°

3x = 180°

x = 180/3 = 60°

∆ABC = 60° and ∆ ADC = 120°

∆BAD = 60° (adjacent angles of a trapezoid add up to 180°)

As shown in the figure attached, part of line AB is equal to 3 units and part is equal to: (c) units * 2 .

[tex] \frac{c}{5} = \cos(60) = \frac{1}{2} [/tex]

c = 2.5 units

Hence length AB is equal to; 2(2.5) units + 3 units = 8 units
